To be honest, I just looked up the report and did not not notice it came from there. My only agenda was that it was the only report that clearly showed the average and CI of the different studies throughout the years. WWF links to the actual report [1] which is found at [2]. They try their very hardest to not show that the population is either stable or increasing. If you look at decreases, for example in Davis Strait, it is a loss of 1% with 0% in the 95% interval.
Anyway, I do admit that linking from that website is not a good look but all I did was link the report and I am not advocating for anything else on their website. My larger point, the climate change community does not need the polar bears to drive their point. It is a bad example and we should use one of the many other verifiable sources (ice sheet loss, sea level rise, droughts, etc.) instead.
